One of the front engine oil seals failed while the vehicle was being driven in local traffic causing all of the engine oil to be pumped out onto the hot engine and exhaust emptying the crankcase in little more than 1 minute. I pulled into a gas station and opened the hood to investigate the smoke and smell of burning oil. The oil on the hot exhaust ignited and was quickly extinguished with the stations garden hose.

Toyota has a known failure issue with the engine oil cooler hose on this model. With this issue, a defect in the hose causes oil to leak rapidly from the hose. A search of the internet can find many instances of this issue, with catastrophic engine failure resulting in certain cases. Toyota has issued warranty enhancement ze2 to cover this. The warranty term for this item is extended to ten years and 150,000 miles. I experienced this failure last week. It occurred as I was pulling into a car wash. Smoke started coming from my engine and the car wash worker noticed oil leaking from underneath. I had to have the vehicle towed and the hose replaced. The total cost was $665. I attempted to get coverage from toyota, but my request was denied due to the fact that the mileage was at 167,000. The reason for my complaint is that a major, known defect such as this should not be time or mileage limited. Given the catastrophic failure that can result from this defect, toyota should have been replacing the defective hoses rather than forcing customers to endure the problems of failure in the field, which often resulted in blown engines and the need to have vehicles towed in for repairs. If toyota is not going to take the step of preventing the problem, they should at least take care of the problem when it occurs - regardless of age or mileage - because the cause is clearly the result of a known defect. I contacted toyota warranty service for reimbursement and my claim was denied. I called back and asked to escalate it. I was transferred to a higher level agent who again denied my claim and told me to address my complaint outside of toyota, which is why I am filing here. With this complaint, I am seeking reimbursement of my $665 costs. I further suggest that toyota be urged to revise warranty enhancement ze2 to remove the mileage and time limits.

While traveling at 75mph on interstate, I noticed heavy white smoke trailing vehicle. Slowed and pulled over. Inspected engine and found large oil leak. No check engine or low oil lights illuminated prior to smoke. Entire bottom of the car coated with oil, including exhaust system, front passenger tire and rear tires. No oil registered on dipstick. Towed to toyota dealer where the car was purchased. Failed part was the oil cooler hose. Technician showed me the faulty rubber hose which had a pin-hole leak and there was barely one half quart in the engine, which holds 6.4 quarts. Judging by how often I had been looking in the rear view mirror due to traffic, I'd estimate the leak was only a few minutes in length and the engine would have been without oil and at highway speed very soon if I hadn't noticed. This is not an extraordinary event until you realize that the oil hose that failed was part of toyota's 90k oil cooler hose limited service campaign for 2gr-fe v6 engines in 2011. I had my car undergo this fix, which simply replaced a rubber hose with another rubber hose which was supposedly made from a compound that better resists hot oil. The replacement hoses are failing, which is what toyota tsb-0201-11 "oil cooler seep" (dec 21, 2011) is meant to cover and it replaces the rubber oil hoses with an all-steel hose. However, it only applies to customers still under the 36,000 mile warranty and with a "seeping" hose. Most 2007 sienna owners, like me, were well past warranty mileage in 2011, had no indication from toyota that the rubber oil hoses were potential problems and are only getting the steel hose after catastrophic engine oil loss. I was billed $532 for the oil cooler hose replacement and quoted $307 to replace the o2 sensor which was damaged by the volume of hot oil that sprayed on it. Huge oil loss at highway speeds. Toyota knows, but many owners do not.

I am the second owner of the vehicle. I was driving on interstate 5 at 65 miles per hours from sacramento to los angeles. The time was 1600 on 13 april 2014. I did not notice any crack or noise from road debris damage while I am diving. The red low oil warning light on the dashboard did not turn on at the time when the incident happened. I was pulled over a rest stop to use restroom; I also walk around the vehicle to conduct a visual check and fluid check at the same time. I was discovered engine oil was all over the engine bay, undercarriage and the back lift door during the visual check. When I checked the engine oil, the dip stick showed no engine oil. Again, the red low oil warning light did not turn on which indicate low engine oil at that time even the engine had no engine oil. Vehicle was towed to toyota dealership and discovered an oil cooler hose which make out of rubber was ruptured. Even the oil cooler hose was replaced with a metal oil hose; the engine was damaged by operated without engine oil for a significant period. Prior to the trip, I purchased the all metal vvt-I hose from a local dealership, again no warning from the dealership. I used a local repair shop to replace the vvt-I hose locate at the passage side of the engine to an all metal pipe since I have knowledge on the rubber vvt-I hose have the same rupture issue. However, I have no knowledge on the t-sb-0201-11 which is the toyota technical service bulletin title oil cooler pipe seep. There is recall regarding shift lock solenoid and severe corrosion of the spare tire carrier cable on the 2007 sienna, however, there is no recall on possible rupture on vvt-I hose or oil cooler hose. If the recall was issued or at least warned by dealership, I will fix the oil cooler hose at the dealer or a local repair shop and avoid the engine damage which leaded to engine replacement.

T-sb-0047-10 from "some vehicles equipped with 2gr-fe/fxe engine. The rubber portion of the oil supply hose for vvt-I actuator may degrade over time. This condition may cause oil to leak from the vvt-I oil hose producing abnormal engine noise and the oil pressure light to illuminate " this tsb affects toyota vehicles going back to at least 2008-present. This is a major issue, and I feel this should be handled as a recall instead of a tsb due to the severity of the issue if/when the pipe breaks. I recently elected to have my vehicle repaired on my own just so I wouldn't have to worry about this issue happening to me or my wife, and thus blowing up my sienna's engine causing thousands of dollars in damages. Seems pretty bad that a recall can be issued for floor mats and accelerator issues, but no recall is issued for this issue which can drain the oil from your engine in a minute, blow up your engine, and then possibly wreck your vehicle. Consumer's engines are now being destroyed, and this is showing up in different online forums. I feel that the federal safety agency needs to force toyota to replace all of the defective engine oil cooler pipes with the newer metal ones that the tsb addresses. They should also be forced to reimburse all costs to those individuals that either needed to have the repair done, or decided to preventatively have the repair done on their own before those pipes burst on their own. Toyota has told me that my vehicle was not affected by their limited service campaign csc-10033553-6074 but my car has seepage from the rubber portion of the hose that was diagnosed by grapevine toyota dealership yesterday. Very sad situation that such a dangerous condition exists in so many toyota vehicles with the v-6 (2gr-fe) engine. Please help!!!

Multiple problems with my 2000 toyota sienna xle, first the car had problems with battery drain and not starting, they replaced the radio amplifier twice before fixing it, the power window on the driver side broke at 35,000 miles. The back hatch sheetmetal is all dented just from closing it and pushing on the handle. The worst one is that the van has been blowing a lot of blue smoke and burning oil, 4 quarts in the last 750 miles. So far no help from the dealer.
